Project: Sea Life Centre, Brighton
Client: Merlin Attractions Operations
Barwin were appointed to carry out testing and analysis of over 1500 sq m of concrete soffit using a Schmidt hammer test for rebound along with cover metre, chloride and carbonation tests. After reporting the test results to the engineer, we were instructed to cut back 1230 sq m of concrete soffit and remove all the original reinforcement and replace it with resin bonded new reinforcement. The concrete soffits were reinstated using Sika Gunite system sprayed onto the soffits and finished by hand with a trowel, this method was adopted only where access was available. In some areas the access was so restricted that hand placing of the repair mortar was the only option. All the new concrete was then coated with a FerroGuard, anti-carbonation migrating system to protect the new reinforcement. Under the engineer’s instruction sacrificial anodes were fixed in place. The soffits were covered further with an anti-carbonation three coat paint system.
In conjunction with the concrete repair works, Barwin undertook the delicate paint stripping to the stone and brick work within the Victorian arcade removing several layers of paint to the ornate capitals by a method of poultice and DOFF system. After the removal of the paint the stone and brickwork were surveyed and in accordance with the local conservation officer’s recommendations, repairs to the stone and brickwork carefully took place. In order to preserve the steel frame of the structure, the steel beams were grit blasted and treated with a specialist Leighs paint system. With the marine tank still in place, the project required intense management and coordination with the client and the engineer to achieve the desired result, which included maintaining the wellbeing of the marine life.
